TL;DR: A secure AODV routing protocol is developed for detection of black hole attack with improvements in the RREQ packet and RREP packet protocols with added security to verify the source and destination nodes.

TL;DR: This work systematically join techniques of encryption and hashing to furnish reliable keyword search over encrypted files in decentralized storage using the block chain system, the architecture remains incorruptible and protects all the confidential files and keywords in a fully controlled file access environment.

TL;DR: In this article, a zone-based clustering with fuzzy-logic approach for dynamic CH selection is proposed to resolve the problem of unbalanced energy dissipation among CHs in the network.

TL;DR: An overview of block chains, the structure of blockchains, consensus algorithms, etc., compares the algorithms based on their utility and limitations and gives the glimpse of various protocols, algorithms, applications, challenges and opportunities in the blockchain domain.

TL;DR: In this paper, the authors proposed a privacy-preserving recommendation system (PRIPRO) that employs HE for securing private user data by collecting accelerometer data and synchronizing with its calendar.
